Product overview

The TNG1047 Masks Bacterial Filtration Efficiency Tester is designed to determine the bacterial filtration efficiency of medical and surgical face masks. It supports testing in accordance with ASTM F2100, ASTM F2101, and EN 14683. The instrument operates by nebulizing a bacterial suspension and directing the aerosol through a series of stages, including two sets of Anderson sieve samplers. One set is used with the test specimen, while the other is used without, allowing for comparative analysis. The tester includes a peristaltic pump, flow meters, and a negative pressure aerosol chamber to ensure accurate measurement of particle retention. The system is equipped with a three-level cleaning system for disinfection liquid, purified water, and airflow to maintain hygiene between tests. The device features a 10.4-inch color touch screen for operation and data transmission via USB. It also includes a leakage protection switch and a front-opening glass door for operator safety and observation. The TNG1047 is suitable for testing materials such as nonwoven fabrics used in medical masks.

Application

Masks Bacterial Filtration Efficiency Tester is used to determine the bacterial filtration efficiency (BFE) of medical face masks, surgical face masks, to identify the protective performance from being exposed to bacterial airborne environments, tester can conduct the tests defined in EN14683, ASTM F2100, ASTM F2101, YY 0469, YY0969.

The bacterial suspension is pumped to the nebulizer, the aerosol will be pushed into the aerosol chamber then delivered into two sets of (Anderson) sieve samplers, one with testing specimen, another without specimen in order to compare the different results.

Designed with two sets of Anderson sieve samplers it is possible to get the results with and without testing specimen at the same time, reduce the bias to the minimum, and the machine has a embed clear 3-level (disinfection liquid, purified water, airflow) cleaning system to ensure the safety after the tests.

Features

10.4-inch high brightness color touch screen, easy to operate.

With USB interface, supporting USB data transmission.

With leakage protection switch, the negative pressure test system and the front opening and closing glass door, that can protect operator safety and provide more convenient way for operator to observe.

Double six stage Anderson sample, compare sampling tests, test result is high accuracy.

The flow of peristaltic pump and the flow rate of microbial aerosol generator can be set.

The inner layer of the cabinet is made of stainless steel, and the outer layer is sprayed with cold-rolled sheet, more stable and reliable.
